5 of Missouri, have Invented certain newand useful Improvements inCoffee-Unis, of which the following is a speciiication.

, This invention relates to codec-urns of thatv class usually employedin hotels and restaurants and is deslgned more especially as animprovement in the coffee-urn covered by Patent No. 814960 issued to theCombination Urn Manufacturing Co. of Chicago, Ill., as assignee, onMarch 13, 1906, the object of this invention being to roduce auefficient and 'reliable coiiee-urn o that type whereby boiling watermaybe s rayed upwardly through a mass of ground coffee for the purposeof agitating and thus come into more intimate relation with the groundcoffee and thus produce liquid codec quickly A' further object is toproduce means whereby the liquid coffee can be umped from the bottom ofthe liquid-codee-containin receptacle and forced through the groun-c'oiieein the bag back into said receptacle and thus eliminate thenecessity of drawing off the coiiee through the faucet and pouring itback into the receptacle as commonly practiced, for the purpose ofmixing it thoroughly and making it of uniform strength and quality. L

.With these general objectsin viewfand `others as hereinafter ap ear,the invention consists in certain nove and peculiar features.A ofconstruction and organization.v as hereinafter described and claiined;and in order that it may be fully understood reference is to be had tothe accompanying .drawine, in which;

cFi ure 1 is a vertical section Vtaken on the line l-I of Fig. 2. Fig. 2is a horizontal section taken on the line Il-II 'of Fi 1. Fig. 3 is anenlarged vertical section o ,the water-spraying nozzle. Fig. 4 is anenlarged vertical section of a part of the ground-coiiee bag. Fig. 5 isa side view of a pump and its immediate connections.

drical tanl; having a raised .bottom 2 and mounted upon supporting legs3. Arranged concentrically within said tank is aliquidcoiieez-eontaining receptacle 4, the saine beorifzontal collar 5fitting snugly within In the said drawings 1 indicates acyliningsnuglylembraced by and suspended from tank 1 near the u per endof the same, and the bottom of said receptacle 4 isprovided With astrainer-covered discharge nipple 6.

7 'indicates a tank-shaped. jacket arranged concentrically Within tank 1and spaced from the same and receptacle 4 to form the Inner Wall of thetank and provide an air chamber 8 immediately surrounding the saidreceptacle., the chamber 9 formed by and between the tank and saidjacket being adapted to be charged with water by a supply pipe notshown, because of common and well own arrangement.

11 indicates a substantially step-sha ed ring suspended from the top ofthe tan 1 into the receptacle 4 and forming a cover for the space orchamber 12 into which tubes 10 discharge, the undermost'or lowest step'of said ring or ring-cover as it will be hereinafter termed,constituting an upwardly disposed shoulder 13 for a purpose which herelmatter appears, and to provide for a proper circulation of the hot airthrough pi es'lO into chamber 12, the tank 1 is forme. with a series ofapertures 14.

15 is an inverted ground-coiiee bag provided at its upper en d with anddependingl 'from a ring 16 which serves to hold the bag open and tosupport the same within recep-A tacle 4 and the inner portion of theringcover by either resting upon the shoulder 13 of the latter or uponthe outturned bead 18 -formed at the lower end of a circular wall 19'which forms an extension for the groundcotfee bag and projects bypreference beyond the upper end of tank 1 to guard against ground-coffeeinthe ba when agitated, overiiowing the tank or t e top-most step of thering-cover, and to compel all of the liquid co'ee to percolate throughthe bag`to enter the underlying receptacle. I prefer toarrange theextension within ring 16 so that the bead of said extensionshallunderlie and form the direct support for'said ring 16 and rest upon theshoulder 13 with tht ontiguous portion of theV bag interposed between itand the shoulder.

. 20 indicates the cap or cover for the tank which serves to retain thearoma and thus communicating throughv branch-'pi es 23 y from elbow 27.it being obvious that it wouldv with a pump 24 having discharge ranchpipes 25 connected to a pipe 26 extending upward and into chamber 12 andthence upward through ring-cover 11 intoA the cap 20 andthen radiallyinwardover the extension 19 of the coffee-bag and terminating centrallyof said extension in a` down-turned elbow 27 from which detachablenozzlel 29 having a series of upwardly and outwardly pitched dischargeorifices 30, as shown clearly in Fig. 3, this nozzle being arranged nlwithin and near the bottom or apex of the inverted conical bag 15 andembedded in or underlying the mass of ground coil'ee with which such bagis charged, the said pipe 28 being preferably provided with the han le3l by which it is screwed into or unscrewed be impracticable to securethe coffee-bag and lts extenslonin or remove 1t from position unlesspipe 28 was supported.

- the latter `to indicate the height of the liquid-coffee standing inreceptacle 4.

42 are tubes surroundingv the ,coffee-discharge spouts 39 within tank 1in order to provide an air space around said spouts to guard against thesame being chilled or unduly heated by V cold or boiling water inchamber 9, the parts 39 to 42 inclusive forming no part of the presentinvention as theyv correspond substantially to parts of the aforesaidpatent.

Assuming now that the tanky 1 is' charged l with the re uired volume ofwater and that as been raised to the boiling point as will beindicated'by steam'escaping through pipe 43 communicating at its lowerend with chamber 9, the person in control removes the cap'20 anddeposits the required quantity of ground coffee in the bag so that itshall completely cover and hide from sight the nozzle 29. lle thenreplaces `the cap and opens valve 33 to permit the pressure of the steamgenerated to cause the hot water from 'chamber 9 to pass through pipe 32into pipe y26 and up through the latter to'pipe 28 and downA through thesame into nozzle 29 from which it esca es outwardly and upwardly in theshape of ine jets, which as will be readily understood, agitate the massvof ground coffee so as to come into contact with every the aroma. v f

From the above description it will be a .parent that this 'coffee u rnembodies t e f right to make such changes as particle of the same, invfact the agitation is so violen-t that the coffee a pears as though itwere boiling. The liqui -coee thus' produced percolates through the bag'into the receptacle 4. When the desired uantity of liquid-collec hasbeen produced. lhe valve 33 is closed and the pump is manipulated for aminute or so, this manipulation of the ump resulting in umping thecofeefrom t e receptacle an causing it to pass through the ground colee andthen renter the receptacle 4, thus in eiect,"repouri'ng the liquid coieeand servin to extract allot the strength and quality. un'ng the. entirecoffee-making and repouring operations vthe ca 2O remains in place so astoguard against t Ie escape of eatures of advantage enumerated asdesirabler in addition tothose of` the urn covered b thepatenthereinbefore referred to, and W 'e :[,have illustrated and described thepreferred embodiment of my invention, it is to. be lunderstood that Ireserve the roperly fall within the spirit and scope of the appendedclaims.
